聚丙烯纤维是经过特殊材料配方和生产工艺加工而成的,其材料的防静电性能和物理力学性能得到改善。普通混凝土材料因存在早期收缩裂缝问题而影响混凝土的抗渗性能,掺加PP纤维的混凝土材料,由于纤维在混凝土材料内部各方向上的随机均匀分布,对材料整体产生微加筋作用,提高了混凝土材料的韧性,明显改善了混凝土的抗裂、抗渗和抗冲击性能,从而抑制了混凝土塑性变形和收缩裂缝的形成,改善了混凝土的整体性,使水工建筑结构更好地适应冻胀变形。
Polypropylene fiber is processed through a special material formula and production process, the anti-static properties and physical and mechanical properties of the material is improved. Ordinary concrete material due to the existence of early shrinkage cracks affect the impermeability of concrete, mixed with PP fiber concrete material, due to the fibers in all directions within the concrete material evenly distributed evenly on the whole material to produce micro-reinforcement effect, increased Concrete toughness, significantly improved the concrete cracking, impermeability and impact resistance, thereby inhibiting the plastic deformation and shrinkage cracks in the concrete to improve the integrity of the concrete, so that the hydraulic structure to better adapt to frost heave Deformation.
